Import Data

I’m trying to clean up the data from my emonTH as previously discussed. I’ve created a new feed with a 60s interval (instead of the crazy 5s interval it gave me automatically) and now I’m trying to use the Import Data facility from the bottom of the Feed View page to put in the historical data.

I’ve taken all the readings to date and converted them into the CSV format it wants, but now I’m a bit stuck. It wants me to “Paste CSV” when I was expecting to “Select CSV File”. There are 56716 lines in the CSV file. How am I expected to select them to copy and paste?

edit: to add. I chose some data, selected it and imported it, and the system said it was imported successfully, but when I try to graph it it seems there’s nothing there? What gives?
